EMBROIDERY-HOOP.

Specification of Letters Patent. Patented Dec, 22, 1914:,

Application filed May 11, 1914. Serial No. 837,625.

To all whom t may concern:

Be it known that I, FRANK C. HALDET, a citizen of the United States, residing in Canton, in the county of Stark and State of Chio, have invented a new and useful Improvenient in Embroidery-Hoops, of which the following is a specification.

My invention has relation to a frame for stretching fabric for the purpose of embroidering or otherwise ornamenting the fabric, and consists of an inner ring, over which the fabric is stretched, and an outer ring adapted to clamp the fabric, collectively known as an embroidery hoop, and especially to that class of embroidery hoop wherein the inner hoop comprises a continuous ring, and the outer hoop consists of an expansible ring adapted to accommodate dierent thicknesses of fabric.

It is the object of my invention to provide an embroidery hoop, of this character, in which the outer or expansible ring is adapted to accommodate varying thicknesses of material and still remain substantially a true circle.

Another object is to provide means whereby under all conditions the outer or expansible ring will clamp the fabric at all points around the periphery of the inner ring.

These objects, together with other objects readily apparent to those skilled in the art, may be attained by the construction disclosed in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the drawings; Figure 1 is a perspective view of the inner and outer rings separated from each other to better illustrate the construction. Fig. 2 is a longitudinal sectional view through a portion of the outer ring, showing the means of connecting the opposite ends. Fig. 3 is a section on the line 3-3 of Fig. l. Fig. 4 is a perspective view of the shoe in which the opposite ends of the detachable ring are located. Fig. 5 is a section on the line 5 5 of Fig. 1. Fig. 6 is a fragmentary perspective view showing one of the ends of the outer ring.

Similar numerals of reference indicate corresponding parts throughout the several views.

The inner hoop 1 consists of a continuous ring provided with the reinforcing beads 2 adapted to Astrengthen the hoop 1 and maintain it in circular form. The construction of the inner ring, however, is imma;A terial to the present invention, it only being necessary `to provide a rigid inner ring over which the fabric may be stretched. 4

The outer, expansible ring 3 consists of a metallic strip provided with the strengthening beads 4 throughout the greater portion of its length, intermediate its ends, and formed into a circle, the opposite ends of said metallic strip being flexibly connected by means hereinafter described.

A curved shoe 5, conforming with the contour of the ring 8, is provided, said shoe being for the purpose of housing the opposite ends of the hoop 3, and for guiding said ends when the hoop is expanded or contracted. The opposite ends of the ring 3 are adapted to contact at a point intermediate the ends of the shoe 5, preferably equidistant from each end of said shoe, and the hoop is provided with a reduced portion at4 either extremity, said reduced portion adapted to slide within the grooves formed by the over-turned flanges 6 formed upon the shoe 5. The reduced portions upon either extremity of the ring extend back from the free ends of said ring to the point where the hoop enters the shoe 5, at which point the beads 4 are flattened against the face of the hoop, as at 7, thus forming shoulders 8 adapted to contact with the ends of the shoe, and an offset 9 is provided at this point thus forming a continuous circular inner face upon the outer ring 3, the inner face of the shoe 5 throughout its length comprising a portion of said circle.

The shoe 5 is of the same width as the ring 3 and as the hoop is provided with the reduced extremities, the beads being flattened against the face of said extremities through the length of the shoe, the width and thickness of the ring 3 will be substantially the same through its circumference. Located in the reduced portion at each end of the ring 8, and preferably stamped therein, is a tang 10 provided with an eye 11 adapted to receive the opposite hooks 12 of a coil spring 18, said spring being located between the over-turned flanges 6 formed upon the shoe, said flanges also forming a guide for the spring.

In embroidery hoops of this character where the outer hoop consists of a split ring adapted to be expanded, difficulty has been found in maintaining a true circle as thus expanded. It is necessary that the outer ring at all times should conform to the outline of the inner ring in order to clamp the fabric at all points around the circumference and when the outer ring is thrown out of a true circle by expansion it Will be readily seen that there Will be some points around the circumference of the inner ring at Which the fabric Will not be tightly clamped. the present invention the shoe dforn'isv a considerable portion of the inner circumference of the outer ring and tends to hold the outer ring in substantially a true circle, under all conditions.

` 'claimt- In an embroidery hoop, an inner rigid ring and an outer split ring provided With strengthening beads upon its outer face at its upper and lower edges, the adjoining end portions of said split ring being reduced and oH-set, said strengthening beads being flattened 'against the ring at said otfset reducedend portions, said volli-set and reduced ends 'slidably mounted Within a detachable shoe conforming With the contour` of said ring, the inner face of said shoe forming a portion of the inner surface of the outer ring, spaced, back turned flanges located at the upper and lower edges of said shoe forming channels along the upper and lower edges of said shoe and upon the outer face tliereoi', the reduced oil-set portions of the split ring being slidably mounted Within said channels, said flattened portions of the strengthening beads being located Within said channels, a tang provided upon each of the reduced end portions of the split ring and a coil spring connected to said tangs, said coil spring being located between the upper and loiver spaced flanges upon said shoe.

In testimony that claim the above, l have hereunto subscribed my name in the presence of two Witnesses.

FRANK C. HAIDET.
